Milky Way and Andromeda Galaxies Have the Same Mass

February 16, 2018

In 2012, NASA astronomers predicted that our Milky Way galaxy will collide and merge with its neighboring Andromeda galaxy in about 4 billion years. Scientists said that when this galactic collision takes place, Andromeda, which was thought to be two to three times the size of the Milky Way – will completely engulf our galaxy. Now, […]

Is Planet 9 Causing Our Solar System to Wobble?

October 20, 2016

A new study from researchers at the California Institute of Technology (Caltech) suggests that Planet 9, the huge and so far unseen planet said to be lurking in the far reaches of the solar system, might be causing our group of planets to wobble a little and giving an impression that the sun is slightly tilted. […]

Astronomers Find Massive Star Making Galaxy Cluster

September 12, 2015

Astronomers have discovered a distant and massive galaxy cluster with a gigantic and prolific galaxy at its heart that’s pumping out hundreds of stars each year. The galaxy cluster is named SpARCS 1049+56 and is located about 9.8 billion light years from Earth in the Ursa Major constellation. Galaxy clusters are areas of the universe […]
